Publication number: 20240023952Abstract: A tissue anchor includes a central body extending between a first lengthwise end and a second lengthwise end. A first arm extends outwardly from the central body, and a second arm extends outwardly from the central body and spaced from the first arm. The tissue anchor is movable between a collapsed state and a deployed state. In the collapsed state, the central body extends linearly from the first lengthwise end to the second lengthwise end of the central body along an axis and the first and second arms extend parallel to the axis. In the deployed state, the central body extends non-linearly and the first and second arms extend radially outwardly from the central body.Type: ApplicationFiled: May 17, 2023Publication date: January 25, 2024Inventors: John A. DeFord, Krasnodar Ivancev

Patent number: 11452590Abstract: A stent graft (2) for placement in the thoracic arch of a patient has a first tubular body portion (6) with a first lumen therein for placement in the ascending aorta of a patient and a second tubular body portion (8) to extend along the thoracic arch and down the descending aorta. The second tubular body portion is of a lesser diameter than the first tubular body portion. There is a step portion (10) between the first body portion and the second body portion. The step portion is joined to and continuous with the first portion and the second portion. A first side of each of the first body portion, the step portion and the second body portion are substantially aligned so that there is a step (18) defined on a second side opposite to the first side of the body portion. There is an aperture (30) in the step portion and an internal tube (32) extending from the aperture towards the first body portion.Type: GrantFiled: July 20, 2021Date of Patent: September 27, 2022Assignee: Cook Medical Technologies LLCInventors: David E.

Patent number: 9498361Abstract: An endoluminal prosthesis includes an expandable stent graft that includes a cannula extending through a lumen of the stent graft. A suture is threaded along the perimeter of the graft through openings therein, with an inner end of the suture mounted to the cannula. The cannula is rotatable relative to the graft to wind or unwind the suture around the cannula and cause the graft to become compressed when wound or allow the graft to expand when unwound. The cannula includes an attachment member for retaining an inner end of the suture, and the attachment member can release the inner end of the suture when adjustment of the graft diameter is no longer desired.Type: GrantFiled: December 18, 2013Date of Patent: November 22, 2016Assignee: Cook Medical Technologies LLCInventors: Blayne A.
